the perimeter of a Rhombus is sum of all sides
here we don't know the sides but we do know the diagonals
so applying the Pythagoras therom
but issue is we know the complete lenght is the diagonal but we need only from the midpoint
so half the diagonal is 12cm and 5cm
so 12^2+5^2=144+25=169
√169=13
thus one side is 13 so perimeter is 13+13+13+13=52
thus perimeter is 52

if you apply Heron's formula it is used to calculate the total area of a triangle but here it is perimeter that is asked so I don't know why they gave you that in Heron's formula chapter
